- Nine new color names: from pink and purple to orange and latte.
Since 4.0:
- Pasting from outside into nano suppresses auto-indentation.
- Such an external paste can be undone with a single M-U.
- Shift+Meta+letter key combos can be bound with 'bind Sh-M-letter ...'.
- A custom nanorc file may be specified with -f / --rcfile.
- What the <Tab> key produces can be specified per syntax with 'tabgives'.
- The ability to perform a search at startup with +/string or +?string.
- Comment characters are copied when automatic hard-wrapping occurs.
- The ability to both read from and write to a FIFO.
- Automatic hard-wrapping is no longer the default.
- Addition of --guidestripe to draw a helpful vertical bar.
- Meta-Up and Meta-Down scroll the screen linewise.
- Continuation is shown with a highlighted ">" instead of a plain "$".
- A marked region gets justified into a single, separate paragraph.
- Any number of justifications can be undone.

- Addition of --zap to make <Del> and <Bsp> obliterate marked text.
- <Ctrl+Delete> wipes next word and <Shift+Ctrl+Delete> preceding word.
- An external spell check can be undone.
Since 2.9.0:
- The ability to filter text through an external command.
- Better detection of paragraphs, allowing a less indented beginning.
- Option 'set afterends' for making Ctrl+Right stop at word ends.
- A crash handler that saves changed buffers in case of a crash.

- The ^G help texts have become searchable (with ^W and M-W).
- Ctrl+Home and Ctrl+End jump to start and end of file.

per logical line, and the screen will scroll per row.

Since 2.5.0:
- The option 'justifytrim' for snipping whitespace from justified lines.
- The ability to discard a buffer (^O ^Q) when --tempfile is used.
- On most terminals Ctrl+Left / Ctrl+Right now work for PrevWord/NextWord.

- The ability to save a file without prompting for its name ('savefile').
- The ability to search backward without having to toggle the direction.
Since 2.4.0:
- Replacing things in a marked region now takes place in situ, in context,
instead of changing the view to only the marked text.
- Invalid byte sequences are properly displayed and not mistakenly found.
- Resizing the window does not exit from help viewer nor file browser.
Since 2.3.0:
- System syntaxes can be improved upon with the 'extendsyntax' command.
- Whitespace display (M-P) does not require configuration to be useful.

-- just not yet for justifying and indenting/unindenting.

- The ability to run a linter or formatter (^T) on the current buffer.
- The ability to only write to named pipes with --noread.

- The ability to silence nanorc error messages (-q).

it won't try to write the original file afterward.
- Emergency savefiles retain ownerships and permissions when possible.
- Performance improvements in color syntax highlighting.
Since 1.2.0:
- Support for UTF-8.
- Moving to a specified line and column of a file, instead of just a
line (+LINE,COLUMN).

- Insertion of spaces instead of a tab when Tab is pressed (-E).
- The long option for -K is now --rebindkeypad.
- Regular expression searching can now be toggled when nano is built

the ability to specify background colors without foreground colors...
- Insertion of single-byte characters via Esc Esc <000-255>.
- Insertion of any character via Meta-V, "Verbatim Input".
- Workaround for the "NumLock glitch".

the "Search" prompt.
- Searching for filenames in the file browser.
- Spaces and tabs are shown differently to make it easier to tell them apart.

previous word, searching for matching brackets, "Verbatim Input"...
- "To Line" (^W^T) and "Read from Command" (^R^X) return to their parent
menu when their keystroke is entered again (^W^T^T and ^R^X^X).
- Automatic adding of newlines to the ends of files without them can
now be disabled (-L).
- Converting from and to DOS/Mac file format is now toggled only at the
"Write File" prompt, via Meta-D and Meta-M, and the default file format
to save in is now set depending on what format the file was originally
in. -D now makes nano use bold text instead of reverse video text,
and Meta-D at the edit window now does a word/line/character count.
-O now makes the unused second line of the screen part of the edit
window, and Meta-O now toggles this behavior while editing.
- Converting files that contain a mix of DOS and Mac format lines.
- Automatic switching on of -N with binary files has been removed, as
it causes problems with UTF-8 support.
Since 1.0
- Complete Pico compatibility (option --pico has been removed,
and -p now means something else, see below).

- Jumping to the matching brace, bracket, etc.
